,老师您好，我是小，实在抱歉好久没和您联系了。我在做题中有很多的问题不明白特地向老师请教。Alice had a wonderful time yesterday, ？A：had not she B：was not she C：did not she Dwonld not she老师，我已知道句中had不是完成时态，但我不明白为甚莫在这个反义疑问句要用 did来反问呢？答案是BThere are many people downstairs.What do you think ?A:to happen B:happening C:is happened D：has happened 答案为D 请教老师happen不是没有被动语态吗。，是不是答案给错了？如果不是D，请问老师应该是哪项呢？

,Alice had a wonderful time yesterday, ？A：had not she B：was not she C：did not she Dwonld not she老师，我已知道句中had不是完成时态，但我不明白为甚莫在这个反义疑问句要用 did来反问呢？答案是Bhad 是过去时，所以用did反问。第二题，出错了，正确为：There are many people downstairs .What do you think ? A to happen. B is happening. C is happened.D：was happenedB 首先呢，happen""发生""不能用于被动语态，C D排除。第二，句中""do you think""是插入语，可以隔过去不看，what作主语，句中缺谓语，而动词不定式(to do)属于非谓语动词，即不能直接作谓语。排除A。第三捏，根据句意知，“楼下有许多人。你认为现在发生了什么事？”“发生”这个动作是正在进行的，用现在进行时。综上知，选B.
